Routine service items

These are the items covered in a standard service. Most garages include oil, oil filter and a basic inspection. The rest are typically checked or replaced on a schedule.

Service item	Interval	Typical cost
Engine oil and filter Manufacturer interval 6,000 miles or 6 months. Frequent oil changes critical for carburettor engines. Change filter every oil change. Use 10W-40 mineral oil. SJ413	6,000 miles or 6 months	£40–£60
Air filter Manufacturer interval 12,000 miles. Check more frequently if used off-road. Clogged filter affects carburettor mixture and performance significantly. SJ413	12,000 miles or 1 year	£15–£25
Transfer box oil Manufacturer interval 24,000 miles. Use SAE 80W-90 gear oil same as gearbox. Essential for 4WD system longevity. Check for leaks around output seals. SJ413	24,000 miles or 2 years	£40–£70
Differential oil Manufacturer interval 24,000 miles for both front and rear differentials. Use SAE 80W-90 gear oil. Front diff shares oil with transfer box. Rear diff has separate filler plug. SJ413	24,000 miles or 2 years	£50–£80

Major service items

These are the big-ticket items. Miss them and you risk engine or gearbox damage. The costs are higher but the consequences of skipping are much worse.

Service item	Interval	Typical cost
Gearbox oil Manufacturer interval 24,000 miles. Use SAE 80W-90 gear oil. Check level monthly via filler plug. Low oil causes bearing wear and difficult gear selection. SJ413	24,000 miles or 2 years	£50–£80

Periodic maintenance

Items that don't need doing at every service but should be on your radar at the right mileage or age.

Service item	Interval	Typical cost
Spark plugs Manufacturer interval 12,000 miles. Use correct heat range for carburettor engines. Gap to 0.7-0.8mm. Incorrect plugs cause poor idle and fuel consumption. SJ413	12,000 miles or 2 years	£25–£40
Brake fluid Manufacturer interval 2 years regardless of mileage. DOT 3 or DOT 4 specification. Hygroscopic fluid absorbs moisture which reduces boiling point and causes internal corrosion. SJ413	2 years	£40–£60
Coolant flush Manufacturer interval 24,000 miles or 2 years. Use ethylene glycol antifreeze with corrosion inhibitor. Flush radiator completely - old coolant causes internal corrosion. SJ413	24,000 miles or 2 years	£60–£90
